, the work to a mangle. Heretofore it has been thepractice to use apronsinthe form of a single wide band, but it is found fdiliicult to forcesuch an apron'to runstraight and true owing to uneven stretching ortension, with the result that the aprons weresoon worn out andconstituted a heavy item of'ex-pense in the upkeep of'the machines. Insome cases a number of narrow apron bands have been substituted for thesingle broad apron, these bands having been made in a strip andtheir-edges joined together. Such bands very soon tear atthe joint andare also an item of considerable expense.

It is the object of my invention tov produce an endless woven apronband.

Such a band is shown in the drawings,

I igure 1 being a general perspective view,

and Fig.2 is a transverse section on anenlarged scale to illustrate therelative thickness of the face and back of the belt.

As seen from the drawing the band made in accordance with my inventionis of double thickness, the face being of heavy material, glvingstrength and wearing qualities, and

the back being of lighter material, giving stiffness and weight.

The method of manufacture is follows :''The tubular form is given in theweaving, and assuming that the band is to be 3 inches in width, 1 weavefirst an inch and a half strip of the lighter material for the back,then a three inch strip as A of the heavy material for the face, then athree inch strip of thelighter material, and then I alternate with threeinch strips of heavy and Specification of Letters Patent.
